Centrifugation is a process that uses centrifugal force to separate mixtures based on density differences. It works by spinning samples at high speeds, causing denser particles to sediment out of solution. There are two main types - preparative centrifugation which separates large amounts of samples, and analytical centrifugation which analyzes small amounts. Centrifugation has many applications including isolating suspensions, isotope separation, and separating cellular components.
Centrifugation is the separation technique commonly used in clinical and research laboratories.
It is based on the behavior of particles in an applied centrifugal field.
More dense components of the mixture move away from the axis of the centrifuge while less dense components of the mixture move towards the axis.
Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The larger the size and the larger the density of the particles, the faster they separate from the mixture.

A centrifugation is a technique for separating particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.
A centrifuge operates by using the sedimentation principle- Here the substances are separated based on their density under the influence of gravitational force. When spun rapidly, lighter particles stay at the top and heavier particles go to the bottom during centrifugation.The components of heterogeneous mixtures are detached by centrifugation. That comprises liquids in liquids, solids in fluids, and gases in solids and liquids. In order to transfer bulky sections to the outside of the pipe, centrifugation uses centrifugal energy. It allows the solid to settle more easily and completely.The components of heterogeneous mixtures are detached by centrifugation.

What is the centrifuge used for?
Centrifuges work by separating out two materials with different densities. Centrifuges are used in various laboratories to separate fluids, gases or liquids based on density like the separation of different constituents of blood, immiscible liquids, wastewater sludge etc.
Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. The tube is then placed in a rotor and spun at a define speed.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. INTRODUCTION
• Centrifugation is a process which involves the
use of the centrifugal force for the
sedimentation of heterogeneous mixtures with
a centrifuge, used in industry and laboratory
settings.
• This process is used to separate two
immiscible liquids.
3
5. DEFINITION
• A centrifugation is a
technique for
separating particles
from a solution
according to their
size, shape, density,
viscosity of the
medium and rotor
speed.
5
6. CENTRIFUGE
• A centrifuge is a part
of equipment that puts
an object in rotation
around a fixed axis
(spin in a circle),
applying a potentially
strong force
perpendicular to the
axis of spin.
6
7. PRINCIPLE
• In a solution, particles whose density is higher than
that of the solvent sink (sediment), and particles that
are lighter than it float to the top.
• The greater the difference in density, the faster they
move. If there is no difference in density (isopycnic
conditions), the particles stay steady.
• To take advantage of even tiny differences in density
to separate various particles in a solution, gravity can
be replaced with the much more powerful
“centrifugal force” provided by a centrifuge.
7
8. COMPONENTS OF CENTRIFUGE
• Motor- which give rotator motion.
• Drive shaft- attached to motor.
• Rotor- placed on drive shaft having space to
place tubes.
• Centrifuge rotor: a rotor is the rotating unit of
the centrifuge, which has fixed holes drilled at
an angle. Test tubes are placed inside these
holes and the rotor spins to aid in the
separation of the materials.

12. TYPES OF CENTRIFUGATION
Preparative centrifugation:
• it is a preliminary step to separate component for
further separation and analysis. It can handle large
amount of samples. Its divide 2 types:
• Density gradient centrifugation
• Differential velocity centrifugation
Analytical centrifugation:
• we analyze the sample so small amount is used
few micro-gram/ L to 1 mL
• Mostly ultracentrifuge is used
12
13. DENSITY GRADIENT CENTRIFUGATION
• Under centrifugal force, the particles will
begin sedimenting through the density
gradient.
• Two type of this-
1. Rate zonal centrifugation
2. Isopycnic centrifugation
13
20. ULTRACENTRIFUGATION
• The ultracentrifuge is a centrifuge optimized
for spinning a rotor at very high speeds,
capable of generating acceleration as high as
19600 km/s² (around 50000 rpm).
• Example: Red cells may be separated from
plasma of blood, nuclei from mitochondria in
cell homogenates, and one protein from
another in complex mixtures.
20
29. CONCLUSION
• The centrifugation is a modern and easy
technique of separation.
• Due to centrifugation it is easy to separate
cellular and sub cellular components.
• It is used to study the effects of centrifugal
forces on cells.
• But it is costly and problem to maintenance.
